General Introduction of the JCM & the JCM-REDD+

Basic Concept of the JCM

  • Facilitating diffusion of leading low carbon technologies, products, systems, services, and infrastructure as well as implementation of mitigation actions, and contributing to sustainable development of developing countries.
  • Appropriately evaluating contributions from Japan to GHG emission reductions or removals in a quantitative manner and use them to achieve Japan’s emission reduction target.
  • Contributing to the ultimate objective of the UNFCCC by facilitating global actions for GHG emission reductions or removals.

About the JCM-REDD+

  • REDD+ is one of the potential sector of the JCM.
  • Japan contributes to reduce GHG emission through implementing REDD+ activities
  • The JCM credits are shared

The credits are generated through MRV of the GHG emission reductions or removals achieved by the activities and shared among the project participants and/or both countries taking into consideration their contribution

Features of the JCM-REDD+

  • Flexibility in rules

As the JCM is based on the bilateral documents, national circumstances can be reflected in the implementation rules

  • Upfront funding

The JCM-REDD+ can provide upfront funding to implement REDD+ activities to reduce deforestation and/or forest degradation which is essential for achieving results

  • Private sector involvement

The JCM-REDD+ aims for private sector participation in REDD+

  • Rural development and poverty alleviation

JCM-REDD+ projects are expected to directly involve local communities and contribute to improving their livelihoods

Where a submission including a proposed methodology, PDD and accompanying additional/supporting documents contains information that the methodology proponents or project participants wish to be treated as confidential or proprietary, those entities are required to submit documentation in two versions:
(a) One version where all parts containing confidential or proprietary information are made illegible (e.g. by covering those parts with black ink or overwrite those parts with letters such as “XXX”) so that the version can be made publicly available without displaying confidential or proprietary information;
(b) Another version containing all information that is to be treated as strictly confidential or proprietary by all parties handling this documentation (the third-party entities, the Joint Committee members, external experts).

Prey Lang forest conservation initiative in Stung Treng

Prey Lang, Spanning four provinces, Stung Treng, Kratie, Kampong Thom and Preah Vihear, located in the northeast of Cambodia, along the west bank of the Mekong River, is one of the largest tropical lowland evergreen forests in Indochina and the largest protected area in all of the lower Mekong countries.

Comprised of eight diverse habitats, from dense forest to primordial swamps, Prey Lang provides critical refuge to fifty-five threatened species; including gibbons, Asian elephants and over 250 species of birds.

More than 250,000 people live in 340 villages in close proximity to, and within, Prey Lang, many of whom rely directly on the land for their livelihoods. Most of the population belongs to the indigenous group called Kuy, and the forest also forms part of their cultural and spiritual life.

This critical forest and wildlife within it are under direct threat from illegal logging and wildlife poaching, and deforestation, which is releasing significant greenhouse gases. The conservation of Prey Lang forest has great potential to contribute to broader climate change mitigation efforts.

In March 2018, the Cambodian Ministry of Environment, Mitsui & Co., Ltd., and nonprofit organization Conservation International entered into an agreement to implement a project aimed at reducing greenhouse gas emissions by protecting and conserving the Stung Treng part of Prey Lang forest, through improving livelihoods and law enforcement practices. It is planned to register this project under the Joint Crediting Mechanism (JCM).
